Any of a large group of minerals consisting of hydrated aluminosilicates of sodium, potassium, calcium, and barium. They can be readily dehydrated and rehydrated, and are used as cation exchangers and molecular sieves.
- ‘In the 1970s and 1980s collectors and dealers reported on the zeolites and associated minerals from the Deccan Traps.’
- ‘Four locations in the Wolf Creek Pass area produce a diverse suite of zeolites and associated mineral species that occur as attractive specimens.’
- ‘There are more than eighty different natural zeolite minerals and many hundreds of synthetic zeolites with no naturally occurring equivalents.’
- ‘Exposed zeolites weather rapidly, and consequently good material can be found only in freshly opened cavities.’
- ‘Two zeolite minerals, analcime and natrolite, were identified, representing the first authenticated occurrence of these zeolites in Ontonagon County.’
- ‘Cementation is dominantly by chlorite, with epidote and zeolites also present as cement phases.’
- ‘The junction pockets are commonly lined with quartz and calcite upon which zeolites and associated minerals crystallize.’
- ‘Table Mountain, just north of campus, was once considered one of the world's premier localities for zeolites.’
- ‘He had a wide interest in minerals but specialized in zeolites and published many locality discoveries.’
Late 18th century: from Swedish and German zeolit, from Greek zein to boil + -lite (from their characteristic swelling when heated in the laboratory).
